Samsung Q80C
The Samsung Q80C occupies a key mid to high position within Samsung’s 2023 QLED television lineup. Situated above the edge lit Q60C and Q70C models, but just below the Mini LED equipped Neo QLED series (such as the QN85C), the Q80C is tailored for users who want true local dimming without stepping up to Mini LED price points. Utilizing a Direct Full Array LED backlight paired with Samsung's Quantum Processor 4K, the Q80C offers high peak brightness, a native 120Hz refresh rate, and full HDMI 2.1 features across its ports, making it a popular choice for modern gaming consoles and bright room media viewing. From an internal construction standpoint, the Q80C uses a traditional three board architecture: a dedicated power supply unit (PSU), a main system board hosting the Tizen OS SoC and AV inputs, and a timing controller (T Con) board driving the 4K panel. Larger variants or specific regional builds may integrate the T Con functions directly into the main board or panel driver strips. The television also incorporates a bottom mounted Wi Fi/Bluetooth module connected via a internal ribbon cable and relies on Samsung's rechargeable SolarCell remote for wireless navigation.
